.. The protonated form of caffeine is very soluble in water. The deprotonated form is more soluble in nonpolar solvents. Brewed tea contains tannic acid. When the tannic acid is neutralized by adding a base, the caffeine becomes less soluble in water. H₂C CH3 -N + H+ - H+ N I CH3 Deprotonated Caffeine H3C `N I CH3 CH3 N H Protonated Caffeine If you added sodium carbonate to your tea solution before the extraction, how would that affect your yield?! 1 cause Sodium carbonate is a base this may cause the Caffine to be less soluble in water and will decrease your yield
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
